Answer:

The equation of the line would be y = -2/5x - 2

Explanation:

In order to find this, we first need to find the slope of the first equation. We can do this by solving for y.

5x - 2y = -6

-2y = -5x - 6

y = 5/2x + 3

Now that we have the slope of 5/2, we know that the perpendicular slope is -2/5. We know this because it is the opposite and reciprocal. Now, we can use this along with a point to solve in point-slope form.

y - y1 = m(x - x1)

y - -4 = -2/5(x - 5)

y + 4 = -2/5x + 2

y = -2/5x - 2
